What causes a car window to stick?

It’s a beautiful day out and the perfect opportunity to get some air. You try to roll down your window only to realize that your window is stuck closed. Most drivers may even encounter the phenomenon when their window may become stuck halfway open. What causes your window to become stuck? Below are a few common reasons why your power windows are inoperative: 

Your window’s motor has failed. 
One of the most common culprits to a bad window is a faulty motor. If you’re pressing the window button and the window isn’t activated, the motor will not be able to move the window.

 

The window’s regulator has failed. 
Sometimes your windows motors are still working, but the regulator is broken. The windows regulator moves the glass up and down. If the regulator is malfunctioning, the window may roll up but slide back down on its own. 

A loose or broken window button. 
Over time the windows’ switch can get worn due to frequent usage. One way to test this is if the switch associated with the window isn’t working, see if the master switch on the drive handle does work. This can indicate a faulty button. A defective switch is a simple fix for most automotive shops and is typically inexpensive. 

Dirt, snow, or ice accumulation. 
It’s essential to keep your car clean. If your vehicle hasn’t been cleaned in a while, dirt and grime can jam your car window. Ice and snow can also cause a power window to become stuck. De-ice your windows frequently during winter months to ensure they don’t become damaged or cracked.

When the front windows are operating, but the rear windows aren’t working. 
Some vehicles have child safety latches on the inside of the door handle. Some child safety latches will prevent the door from opening from the inside or prevent the windows from rolling down. If you accidentally knock into this button, press the button again to regain functionality.

If you’re noticing any of these signs, it’s always best to consult a trained automotive specialist. An automotive expert can quickly diagnose the issue and provide a solution. While there are a lot of DIY fixes, it’s vital to trust a professional because window damage can result in costly repairs.
